Adaptive and maladaptive ruminative self-focus during emotional processing

Ruminative self-focus on mood, problems and other aspects of self-experience can have both mal adaptive consequences, perpetuating depression, and, adaptive consequences, promoting recovery from upsetting events. Increasing evidence suggests that these contrasting effects may be explained by distinct varieties of ruminative self-focus, each with distinct functional properties. This study tested the prediction (Emotional processing, three modes of mind and the prevention of relapse in depression. Behav. Res. Therapy, 37 (1999) S53) that an experiential mode of self-focused attention would facilitate recovery from an upsetting event in comparison to a conceptual-evaluative mode of self-focused attention. To test these contrasting effects experimentally, 69 participants wrote about an induced failure experience in either a conceptual-evaluative condition (e.g. "Why did you feel this way?"), or an experiential condition ("How did you feel moment-by-moment?"). Consistent with the hypothesis, higher levels of trait disposition to ruminate were associated with relatively greater increases in negative mood 12 h after the failure in the conceptual-evaluative condition compared to the experiential condition. Furthermore, the conceptual-evaluative condition resulted in more intrusions about the failure than the experiential condition. These results support the differentiation of rumination into distinct modes of self-focused attention with distinct functional effects; a conceptual-evaluative mode that is maladaptive and an experiential mode that is adaptive.     

Using stimulus equivalence‐based instruction to teach young children their caregivers' contact information

Stimulus equivalence‐based instruction (EBI) was used to teach young children of typical development three 4‐member equivalence classes containing contact information from three caregivers (e.g., mother, father, and grandmother). Each class comprised the caregiver's (a) photograph, (b) printed name, (c) printed phone number, and (d) printed name of employer. A pretest‐train‐posttest‐maintenance design with a nontreatment control group comparison was used. Pretests and posttests assessed the degree to which class‐consistent responding occurred across both visual–visual matching tasks and intraverbals. Intraverbal responding was also probed with a novel instructor. Overall, EBI participants scored significantly higher during the posttests than the control participants across both the derived relations and intraverbal tests. These differences maintained 2 weeks later. Thus, responding generalized to (a) a different topography (i.e., intraverbal), (b) auditory versions of the stimuli, and (c) in the presence of a novel instructor. How such procedures may benefit lost children are discussed.     

Revealing negative thinking in recovered major depression: a preliminary investigation

Previous research suggests that formerly dysphoric individuals engage in effortful strategies (e.g., thought suppression) that may mask underlying depressive thinking. The addition of a cognitive load, such as recalling a 6-digit number, which interferes with effortful mental control, reveals depressive thinking in formerly dysphoric individuals. This preliminary study tested whether this effect of cognitive load on revealing negative thinking generalizes to formerly clinically depressed patients. Currently depressed patients, recovered depressed patients and never-depressed patients unscrambled sentences that could form either positive or negative statements, after random allocation to either cognitive load or no cognitive load conditions. The number of negative statements unscrambled was used as an index of negative thinking. Without a load, recovered depressed patients did not differ from never-depressed controls: both groups completed fewer negative statements than currently depressed patients. However, the cognitive load increased negative statements in the recovered depressed group, making them resemble the currently depressed group more than the never-depressed group. These preliminary findings extend previous demonstrations of cognitive load unmasking negative thinking in dysphoric students to a clinical population, suggesting that formerly depressed patients utilize effortful strategies to minimize the report of negative thinking, which is undermined by the addition of a cognitive load.     

Autobiographical memory specificity and emotional disorder

The authors review research showing that when recalling autobiographical events, many emotionally disturbed patients summarize categories of events rather than retrieving a single episode. The mechanisms underlying such overgeneral memory are examined, with a focus on M. A. Conway and C. W. Pleydell-Pearce's (2000) hierarchical search model of personal event retrieval. An elaboration of this model is proposed to account for overgeneral memory, focusing on how memory search can be affected by (a) capture and rumination processes, when mnemonic information used in retrieval activates ruminative thinking; (b) functional avoidance, when episodic material threatens to cause affective disturbance; and (c) impairment in executive capacity and control that limits an individual's ability to remain focused on retrieval in the face of distraction.     

Personality, career decision self-efficacy and commitment to the career choices process among Chinese graduate students

This study examined the mediating effect of career decision self-efficacy on the relationship between the Five-Factor Model of personality and the career commitment process (i.e., vocational commitment and the tendency to foreclose) in a sample of 785 Chinese graduate students. The multiple regression analyses showed that neuroticism and conscientiousness related significantly to progress in vocational commitment both directly and indirectly through career decision self-efficacy. High agreeableness related to less premature foreclosure. In addition, career decision self-efficacy associated with greater progress in vocational commitment but also a strong tendency to foreclose. The implications for career development theory and practice are discussed.     

先天易的数学基础初探——试论先天卦序与二进位制

本文从自然数及其记数法的基本慨念出发。辨析了与二进位制相关的几个容易混淆的概念,指出序数概念的引入在近代数学发展中有重要意义。作为邵雍数学学派的数学基础,先天易是数学史上第一个专门定义的序数体系,该序数体系在数学史上率先采用了二进位制记数法。先天易作为二进制序数体系这一事实在明清时期引起不同的反响,反对者认为它使易道沦落,大数学家汪莱则从P进制的角度论证它的优越性。本文最后还对近年来反对先天易与二进制有关的两种典型观点进行了剖析．指出其谬误所在。
